FIGS. 1A to 1C and 2A to 2C are perspective views of a digital photographing system, according to an embodiment.

Referring to FIGS. 1A to 1C and 2A to 2C, the digital photographing system includes a lens 100, a smart mount 200, and a body 300 (as shown in FIG. 3). In the various embodiments, the body 300 may be a mobile terminal device 301 or a camera body 302.

FIGS. 1A through 1C show the lens 100 and the smart mount 200 connected to the mobile terminal device 301. FIG. 1A is a lateral view of the digital photographing system, FIG. 1B is a diagram showing the mobile terminal device 301 and the smart mount 200 separated from each other, and FIG. 1C is a rear view of the digital photographing system.

FIGS. 2A through 2C show the lens 100 and the smart mount 200 combined with the camera body 302. FIG. 2A is a lateral view of the digital photographing system, and FIGS. 2B and 2C are rear views of the digital photographing system. Although not shown, the camera body 302 and the smart mount 200 may be separated.

FIG. 3 is a sectional view of the digital photographing system shown in FIGS. 1A to 1C and 2A to 2C, and FIG. 4 is a detailed view of the smart mount 200, according to an embodiment.

Referring to FIGS. 3 and 4, the smart mount 200 includes a lens connecting unit 210 for connecting with the lens 100, a shutter 220, an image sensor 230, an image sensor PCB 240, an image processor 250, and a body connecting unit 260 for connecting with the body 300. Although not shown, function buttons for controlling operations for capturing and processing images are arranged outside the smart mount 200, and thus the smart mount 200 may capture and process images autonomously from controls of the body 300.

The image sensor 230 converts light incident via the lens 100 to charges via photo diodes (PD) and converts the charges to voltages. The image sensor 230 may be a charge coupled device (CCD) or a complementary metal oxide semiconductor image sensor (CIS). The image sensor 230 is mounted on the image sensor PCB 240, which includes a circuit for driving the image sensor 230.

The image processor 250 processes data input via the image sensor 230, stores the processed data in a storage unit (251 of FIG. 7) or compresses image data by using a codec, and provides interfaces for external devices.

If image signals input by the image sensor 230 are analog signals, the image processor 250 converts the image signals to digital signals and performs various image processes with respect to the converted digital signals. In detail, the image processor 250 enhances image quality by performing signal processes, such as auto white balance, auto exposure, gamma correction, etc. and outputs image signals with enhanced image quality. Furthermore, the image processor 250 performs various image processes, such as color filter array interpolation, color matrix, color correction, color enhancement, etc.

The smart mount 200 and the body 300 may communicate with each other wiredly/wirelessly. In a case of wired communication, images captured by the smart mount 200 may be transmitted to the body 300 in real time or may be supplied to the body 300 via various interfaces, such as a USB (261 of FIG. 7). In a case of wireless communication, data may be transmitted/received in real time via various communication methods, such as wireless fidelity (Wi-Fi), Bluetooth (BT), near field communication (NFC), etc. As the smart mount 200 supports wireless communication, the smart mount 200 may be linked to not only a dedicated camera body, but also to various mobile terminal devices capable of wireless communication, and thus high quality images may be provided by using a mobile terminal device.

FIGS. 5A and 5B are diagrams showing a combination relationship between the smart mount 200 and the body 300 shown in FIG. 3, according to an embodiment.

Referring to FIG. 5A, if the body 300, which may include the mobile terminal device 301 or the camera body 302, provides a contact point 360, like a conventional camera, the mobile terminal device 301 or the camera body 302 may be connected to the body connecting unit 260 of the smart mount 200 via the contact point 360 or an interface, such as a USB (261 and 361 of FIG. 7). Furthermore, a lens 100 may be connected to the smart mount 200.

Referring to FIG. 5B, the smart mount 200 and the body 300 may be connected to each other via a new adaptor 400 that provides a connection interface. The body connecting unit 260 of the smart mount 200 or a USB (261 of FIG. 7) is connected to a first end 410 of the adaptor 400, whereas the contact point 360 of the mobile terminal device 301 or the camera body 302 or the USB (361 of FIG. 7) is connected to a second end 420 of the adaptor 400. Furthermore, a lens 100 may be connected to the smart mount 200.

FIGS. 6A to 6D are diagrams showing the mobile terminal device 301 shown in FIGS. 1A to 1C downloading and executing an application and to control the smart mount 200, according to an embodiment.

In a case where the mobile terminal device 301 is used as the body 300, it is necessary to download and install a dedicated application for controlling the smart mount 200. Compared to the prior art, which is limited to firmware updates, various applications may be provided by the mobile terminal device 301, and thus the mobile terminal device 301 may modify high-quality images in various ways.

An example of connections between the smart mount 200 and the mobile terminal device 301 may include a Remote Viewfinder. The Remote Viewfinder is an application for connecting a camera to the mobile terminal device 301 to control the camera by using the mobile terminal device 301. First, a user downloads the Remote Viewfinder application from an application store (FIG. 6A) and installs the Remote Viewfinder to the mobile terminal device 301 (FIG. 6B). Next, the Remote Viewfinder is executed on the mobile terminal device 301 to connect the mobile terminal device 301 to the smart mount 200 (FIG. 6C). Here, it may be necessary to enter a password. Next, when the mobile terminal device 301 controls the smart mount 200 (flash on/off, timer, zoom, etc.) and captures an image, the smart mount 200 transmits the captured image to the mobile terminal device 301, and the mobile terminal device 301 displays, stores, or modifies the image (FIG. 6D). The smart mount 200 may be connected to the lens 100.

FIG. 7 is an internal view of the digital photographing system in a case where the body 300 is the camera body 302 as shown in FIGS. 2A to 2C, according to an embodiment.

Referring to FIG. 7, the digital photographing system includes the lens 100, the smart mount 200, and the camera body 302. Here, the camera body 302 may be replaced with the mobile terminal device 301.

The lens 100 collects optical signals from an object. The lens 100 includes a zoom lens for narrowing or widening a viewing angle according to focal lengths, and a focus lens for focusing on an object, etc., where the zoom lens and the focus lens may each include a single lens or a plurality of lenses. The lens 100 transmits collected optical signals to the smart mount 200. The lens 100 includes a first connecting unit 110 for connecting with the smart mount 200.

The smart mount 200 captures and processes images and is connected to the camera body 302. The smart mount 200 includes a second connecting unit 210 (identical to the lens connecting unit 360 shown in FIGS. 3 and 4) for connecting with the lens 100.

Furthermore, the smart mount 200 includes the shutter 220, which includes a front curtain (not shown) and a rear curtain (not shown). Here, the shutter 220 may be a focal plane shutter. Generally, a focal plane shutter is a shutter in which two fabric curtains or metal curtains installed right in front of a focal surface of a lens run horizontally or vertically, where a photosensitive material surface is appropriately exposed by adjusting a slit between the two curtains or adjusting moving speeds of the two curtains. A focal plate shutter is generally installed on lens-exchangeable cameras. Such a focal plane shutter is generally installed on cameras with 6×6 cm or smaller frames and determines exposure time by constantly maintaining a running speed of curtains and adjusting only a slit size by using a speed controller or an electrically-controlled electromagnet. The most distinguishing features of a focal plane shutter are that it has lens exchangeability and that it is an easy high-speed shutter.

Optical signals transmitted through the lens 100 form an image of an object on a light receiving surface of the image sensor 230. The image sensor 230 may be a charge coupled device (CCD), a complementary metal oxide semiconductor image sensor (CIS), or a high-speed image sensor that converts optical signals to electric signals.

The image processor 250 processes data input by the image sensor 230 and stores the processed data in a storage unit 251 or compresses image data by using a codec and provides interfaces for external devices.

The image processor 250 may perform image signal processes for image quality enhancement, such as noise reduction, gamma correction, color filter array interpolation, color matrix, color correction, color enhancement, etc. Furthermore, the image processor 250 may generate an image file by compressing image data generated by performing the image signal processes for image quality enhancement or may restore image data from the image file. Image compression formats may be non-lossy or lossy. Examples of the image compression formats may include RAW data, joint photographic experts group (JPEG), JPEG 2000, etc. Compressed data may be stored in the storage unit 251. Furthermore, the image processor 250 may perform various functions such as sharpening, blurring, edge enhancement, image analysis, image recognition, image effects, etc. Examples of the image recognition may include face recognition, scene recognition, etc. For example, various processes such as brightness level adjustment, color correction, contrast adjustment, edge enhancement, screen splitting, generation of character images, image synthesis, etc. may be performed.

Furthermore, the image processor 250 may receive control signals transmitted from the camera body 302 for various operations, such as photographing, auto-focus, zoom change, focus change, auto exposure correction, shutter driving, etc., perform corresponding operations, and control operations of components.

A dust removing unit 252 includes a dust sensor (not shown) and a piezoelectric device (not shown) for removing dust attached to the image sensor 230. The dust sensor may be a photo detector (not shown) for detecting light that is incident to the image sensor 230 and scattered by dust particles. The dust sensor may include a light transmitting unit (not shown) and a light receiving unit (not shown), where the light transmitting unit emits light toward dust attached to the image sensor 230, and the light receiving unit receives light reflected by the dust. The piezoelectric device vibrates the image sensor 230 according to a vibration signal. Generally, a piezoelectric device is a device that, when a crystal having an asymmetric crystalline structure is mechanically deformed by an external force, charges are induced to a surface of the crystal, electric polarization occurs, and thus subtle charges are generated. Such a piezoelectric device may have induced therein a mechanical deformation simultaneously as charges are formed by applying an electric field to the crystal. In other words, when a high frequency power corresponding to a resonance frequency unique to a piezoelectric device is applied to the piezoelectric device, the piezoelectric device vibrates at its resonant frequency. The dust removing unit 252 detects an amount of dusts via the dust sensor and transmits a vibration signal to the piezoelectric device, so that dust attached to the image sensor 230 is shaken off.

Furthermore, the smart mount 200 may include a button 253. Here, the button 253 refers to a button capable of independently driving the smart mount 200 without control of the camera body 302, e.g., a shutter-release button for inputting a shutter-release signal for capturing an image by exposing the image sensor 230 to light for a predetermined period of time or a power button for turning the smart mount 200 on/off in a case where the smart mount 200 includes a battery.

A user interface 254 receives input of the button 253 and transmits a corresponding signal to the image processor 250.

When smart mount 200 is connected to the camera body 302 via a USB 261, various signals are transmitted to the camera body 302 via the USB 261.

A power connecting unit 262 receives power from the camera body 302 and supplies the received power to a power unit 270. Here, if the smart mount 200 is connected to the camera body 302 wiredly, the power connecting unit 262 and the power unit 270 operate based on power transmitted from the camera body 302. However, if the smart mount 200 is connected to the camera body 302 wirelessly, the smart mount 200 includes its own battery (not shown) and operates therewith.

The camera body 302 receives an image captured and processed by the smart mount 200 and displays, stores, deletes, or modifies the image.

The camera body 302 includes a hot shoe 310, a flash 320, a microphone 331, a speaker 332, an audio processing unit 333, a display unit 340, a display unit interface 341, a control unit 350, buttons 351, a user interface 352, a first USB 361, a power connecting unit 362, a second USB 363, an SD 364, a USB interface 365, a SD card interface 367, a battery 370, and a power unit 371.

The hot shoe 310 is a flash connecting unit of the camera body 302, and the flash 320 is a light-emitting device for momentarily illuminating an object in a case of photographing in a dark environment.

The microphone 331, the speaker 332, and the audio processing unit 333 may output audio signals to perform functions including notification of an operating status during a photographing operation. Type and volume of audio signals of the speaker 332 may be controlled by the audio processing unit 333.

The display unit 340 displays image signals transmitted from the smart mount 200 to a user as a predetermined image. The display unit 340 may also function as a viewfinder unit that continuously displays image signals acquired by the image sensor 230 during a photographing operation to determine a photographing range. The display unit 340 may be any of various types of display devices, such as a liquid crystal display (LCD), an organic light emitting display (OLED), an electronic display device (EDD), etc.

The display unit interface 341 transmits and receives various control signals for driving the display unit 340 under control of the control unit 350.

The control unit 350 processes data based on a stored operating system and application programs, temporarily stores a result of the processing of the data, and controls a corresponding component according to the result of the processing of the data. Particularly, the control unit 350 provides live-view images transmitted from the smart mount 200 for determining a photographing range to the display unit 340, transmits an image capturing signal to the smart mount 200, and displays an image captured by the smart mount 200 on the display unit 340. Furthermore, the control unit 350 provides various functions for modifying an image displayed on the display unit 340 and stores an image displayed on the display unit 340 or modified in the SD 364 via the SD card interface 367 or to delete an image stored in the SD 364.

The buttons 351 are a unit via which control signals may be input from outside, such as a user. The buttons 351 may include a shutter-release button for inputting a shutter-release signal for capturing an image by exposing an image sensor 115 to light for a predetermined period of time, a power button for inputting a control signal for turning the camera body 302 on/off, a wide angle zoom button and a telescope zoom button for widening or narrowing a viewing angle, a mode selecting button for selecting various modes, such as a text inputting mode, a photographing mode, a playback mode, etc., a white balance setting function selecting button, an exposure setting function selecting button, etc. The buttons 351 may include various buttons as described above. However, the invention is not limited thereto, and the buttons 351 may be embodied in any of various types of user input devices, such as a keyboard, a touchpad, a touch screen, a remote controller, etc. The user interface 352 transmits various button input signals to the control unit 350.

The first USB 361 or the second USB 363 is connected to the USB 261 of the smart mount 200 and transmits and receive various signals.

The power connecting unit 362 is connected to the power connecting unit 262 of the smart mount 200 and transmits power from the battery 370 to the smart mount 200.

Power from the battery 370 is also supplied to the power unit 371 to drive the camera body 302.

The smart mount 200 and the camera body 302 may communicate with each other wiredly/wirelessly. In a case of wired communication, images captured by the smart mount 200 may be transmitted to the camera body 302 in real time or may be supplied to the camera body 302 via various interfaces, such as a USB 261. In a case of wireless communication, data may be transmitted/received in real time via various communication methods, such as wireless fidelity (Wi-Fi), Bluetooth (BT), near field communication (NFC), etc. As the smart mount 200 supports wireless communication, the smart mount 200 may be linked to not only a dedicated camera body, but also to various mobile terminal devices capable of wireless communication, and thus high quality images may be provided by using a mobile terminal device.

If the smart mount 200 and the camera body 302 are connected to each other wiredly, the smart mount 200 and the camera body 302 may perform data communication with each other via the USBs 261 and 361. However, if the smart mount 200 and the camera body 302 are connected to each other wirelessly, although not shown, the smart mount 200 and the camera body 302 include wireless communication modules, and thus the smart mount 200 and the camera body 302 may perform data communication with each other via the wireless communication modules.

FIG. 8 is a flowchart showing a method of operating a digital photographing system, according to an embodiment.

Referring to FIG. 8, a user attaches the smart mount 200 combined with the lens 100 to the body 300 (operation S801). Here, the smart mount 200 includes the shutter 220, the image sensor 230, the image sensor PCB 240, and the image processor 250 for capturing and processing images. Furthermore, the body 300 may be the mobile terminal device 301 or the camera body 302 for displaying, modifying, deleting, or storing images captured and processed by the smart mount 200.

When the smart mount 200 is attached to the body 300 and power is supplied thereto, the body 300 determines whether the body 300 to which the smart mount 200 is currently attached is the mobile terminal device 301 or the camera body 302 (operation S803).

If the body 300 is the mobile terminal device 301, it is determined whether a smart mount driving program exists (operation S805).

If no smart mount driving program exists in the mobile terminal device 301, a user may download a smart mount driving program from an application store (e.g., Remote Viewfinder) (operation S807) and execute the smart mount driving program (operation S809).

A photographing angle is set while live-view image is displayed on the mobile terminal device 301 or the camera body 302 (operation S811).

When the photographing angle is set, a user presses the shutter-release button arranged on the mobile terminal device 301 or the camera body 302 (operation S813).

According to a shutter-release button input signal, the smart mount 200 captures an image of the current photographing angle and processes the image to displayable image signals (operation S815).

Next, the smart mount 200 transmits the displayable image signals to the mobile terminal device 301 or the camera body 302 via a wired communication interface, e.g., the USBs 261 and 361 (operation S817).

The mobile terminal device 301 or the camera body 302 displays, modifies, stores, or deletes the image signals received from the smart mount 200 (operation S819).

FIG. 9 is a flowchart showing a method of operating a digital photographing system, according to another embodiment.

Referring to FIG. 9, a wireless communication environment is established between the smart mount 200 attached to the lens 100 and the body 300 (operation S901). Here, the smart mount 200 includes the shutter 220, the image sensor 230, the image sensor PCB 240, and the image processor 250 for capturing and processing images. Furthermore, the body 300 may be the mobile terminal device 301 or the camera body 302 for displaying, modifying, deleting, or storing images captured and processed by the smart mount 200. When a user turns on the smart mount 200 and the body 300, the body 300 transmits a signal indicating initiation of wireless communication to the smart mount 200, and the smart mount 200 receives the signal indicating initiation of wireless communication, a wireless communication environment is established between the smart mount 200 and the body 300. The smart mount 200 and the body 300 include wireless communication modules, and thus the smart mount 200 and the body 300 may perform wireless communication with each other.

When the wireless communication environment established between the smart mount 200 and the body 300, the body 300 determines whether the body 300 to which the smart mount 200 is currently attached is the mobile terminal device 301 or the camera body 302 (operation S903).

If the body 300 is the mobile terminal device 301, it is determined whether a smart mount driving program exists (operation S905).

If no smart mount driving program exists in the mobile terminal device 301, a user downloads a smart mount driving program from an application store (e.g., Remote Viewfinder) (operation S907) and execute the smart mount driving program (operation S909).

A photographing angle is set as viewing live-view images displayed on the mobile terminal device 301 or the camera body 302 (operation S911). Since the smart mount 200 is not physically attached to the mobile terminal device 301 or the camera body 302 and is wirelessly connected to the mobile terminal device 301 or the camera body 302, a user may move the smart mount 200 and set a photographing angle. Here, a photographing angle set by the smart mount 200 is displayed as live-view images on the mobile terminal device 301 or the camera body 302 wirelessly.

When the photographing angle is set, a user presses the shutter-release button arranged on the mobile terminal device 301 or the camera body 302 (operation S913).

According to a shutter-release button input signal, the smart mount 200 captures an image of the current photographing angle and processes the image to displayable image signals (operation S915).

Next, the smart mount 200 wirelessly transmits the displayable image signals to the mobile terminal device 301 or the camera body 302 via a wireless communication interface (not shown) (operation S917).

The mobile terminal device 301 or the camera body 302 displays, modifies, stores, or deletes the image signals received from the smart mount 200 (operation S919).

In a conventional lens-exchangeable camera system, it is impossible to simultaneously embody both high optical performance of lenses and compact design due to a flange-back distance, that is, a distance between a mount or a rear surface of a lens and a sensor or limits for securing back focus. Therefore, in a conventional lens-exchangeable camera system, both an image sensor and an image processor exist within a camera body, and thus the camera body becomes large and heavy. Furthermore, there are many other inconveniences, e.g., it is necessary for a user to perform additional tasks for communicating with an external mobile terminal device. However, according to the various embodiments, the smart mount 200 including the lens 100, the shutter 220, the image sensor 230, and the image processor 250 is provided separately from the camera body 302 or the mobile terminal device 301, and thus a size of a digital photographing system may be significantly reduced.

Although a camera unit exchangeable camera system has more flexibilities than a lens-exchangeable camera, it is necessary that a dedicated connector be used. Furthermore, there are other technical problems. For example, users must use camera unit exchangeable camera dedicated bodies, and communication with other mobile terminal devices is difficult. However, the smart mount 200 may be connected to various mobile terminal devices, and the smart mount 200 may be controlled on the mobile terminal device 301 by using a dedicated application. Furthermore, high-quality image data may be acquired by using the mobile terminal device 301.

An iPhone camera lens mount is an adaptor for simply connecting conventional DSLR lenses to an iPhone. In a case of displaying an image on an iPhone by using the adaptor, the image is displayed upside down. The reason is that light input through a lens is input as-is to a camera attached to an iPhone. In a case of an iPhone camera lens mount, images are captured and processed by an iPhone. Therefore, quality of the images is the same as that of images captured by using conventional mobile terminal devices. However, since the smart mount 200 includes the image sensor 230 and the image processor 250, all operations are performed by the smart mount 200, and only results of the operations are transmitted to the mobile terminal device 301 or the camera body 302. Therefore, compared to an iPhone camera lens mount, the smart mount 200 may transmit high-quality images to the mobile terminal device 301 or the camera body 302, and a user of the smart mount 200 may acquire high-quality images by using the mobile terminal device 301 via the lens 100 and the image sensor 230 with higher efficiency as compared to a conventional mobile device camera.

Furthermore, a digital photographing system according to various embodiments supports wired/wireless communication. Therefore, the digital photographing system may be linked not only to dedicated camera bodies, but also to mobile terminal devices. Therefore, high-quality images may be captured by using a mobile terminal device, captured images may be easily uploaded to the Internet, and high-quality image modifications may be performed by using a mobile terminal device.
